' l ein all the views A0l the drawings by the same reference characters. f in In the present instance the power transl`mitting device is shown as mounted upon a rar'ne'supported by the legs 1 and comprising the longitudinal side pieces 2 connected at one .end bythe cross bar Q and at an intermediate point by a second cross bar 4 Jour- .vifaled u on the two crass bars 3 and-4 andy dispose longitudinally with res ect to the rameiis thev driving shaft 5 which may receive powerfroma gasolene engine, motor, or othcrsoiirce not shown. shaft is'journaled between the side pieces 2 of the'fram'e at one end thereof and constitutes the driven shaft. Where the transmis- 4sion gearing is employed in connection with l. automobiles this ftransverse shaft 6 may be constituted bythe rear aide of the machine(` A revoluble member 7 is mounted upon the A transverse A drivingl shaft to rotate therewith and cari f ries upon its periphery a continuous track 8 which is formed in sections 8, means being `provided for holding the various sections either in alineinei'it with each other or at .angles to each other. In the latter instance the vtrack 8 becomes irregular and assumes a p zig zag direction. The revoliible member 7 'com' rises a pair of companion disks 7a and 7., t e former being rigid with the driving shaftfwhile the latter-irevolves therewith but is designed to slide longitudinally thereon- In' the periphery of the disk 7a are formedtransverse grooves loosel receiving arms 9 `projecting from tlie' slida ley disk l7". Each ofthe track sections 8a has one. end thereof pivotally connected toV the disk 7 1 as indi.

cated at 10 while the opposite end is pivotally connected at 11 to one of the arms 9, It .,may'also be mentioned thatone end of each of the track sections 8 is formed with aslot for receivi the corresponding pivot pin to permit of t e adjustment to be hereinafter described.- When the slidable disk 7b abuts against the disk 7 a the various sections ofthe track. 8 are in alineinent with each other,

away from the fixed disk 7 the track sections are thrown at angles to each other and the 'track 8 assumes a' zig zag direction, the angies between the' various track'sections depending upon the distance through which the slidable disk?" is moved. Ahead 12 is carried by the slidable disk? l and moves longitudinally uponthe shaft withthe disk, but is Amounted-:tolpermit the disk to rotate inde' nected by a rod 16 t-o a crank 17 upon a shaft pendently thereof. Opposite ends of the head 12 are connected by links 13 to crank arms 14 upon a i'ock shaft 15 journaled within. suitable bearings carried by the cross bar 3. One of the crank arms 14 is also con- 18 having the lever 19 rigidly connected thereto. It will thus be apparent that by swinging the lever 19 the slidable disk 7 can be adjusted longitudinally upon the driving shaft 5 and the various track sections 8 thrown either into alinemcnt with each other or .at the required angle. Y l

Thedriven shaft 6 is designed to be rotated in either direction by means of a clutch mechanism actuated by the revoluble track S, the speed of rotation of the driven shaft depending upon *be angle between the various sections 8** i ,"ie track. A pulley 20 is fast upon the driven shaft 6 and is provided upon its opposite sides with the laterally eX- ytending annular rims`21 formed upon the inner faces with the teeth 22. Loosely mounted upon the shaft 16 uponeaclr side of the pulley 2().,is a sleeve 23, each of the said sleeves having a pair of oppositely extending arms projecting therefrom, the arms 24 carrying a reversible clutch mechanism for cooperating with the teeth 22 while the arms.

25 are formed vwith segmental gearing. This segmental gearing meshes with toothed portions 26 of the connecting rods 27 which are mounted to receive a reciprocating motion from the revoluble track 8.' The extremities of the connecting rods 27 are received loosely within blocks 28 carried by an arch member 29 and the said connectingr rods are each provided with lateral extensions 30 prei jecting upon opposite sides of the track 8, the said extensions preferably having antifriction rollers 31 journalcd thereon for en; gagement with the track. When the various track sections are in alineinent with each other and the driving shaft 5 is rotated the connecting rods 27 assume a `lixed position and no motion is imparted to the shaft '6. However when the track sections 8 are thrown atan angle' to each other aiid the track given a zig 'tag direction the rollers 1 in following the tortuous path of the track impart va reciprocating motion to the connecting rods which produces an oscillatory movement of the arms 24 and 25 and operates through the clutch mechanism to revolve the pulley 2() and the shaft 6. It will be readily apparent that the amplitude ofv the reciprocating movement of the connectsuch amplitude 0f movement of the connecting rods. The driving shaft 5 is designed to be rotated at a uniform s eed and the driven shaft 6 may either be A eld stationary by throwing` the track sections 8 into alineinent with each other or caused to revolve at any re uired speed by properly regulating the ang e between the track sections.

shoe 32 pivotally mounted at an intermediate point upon the extremity of each of the arms 24, the opposite ends of each shoe carrying the pawls 33, the direction of rotation l arm of this bell crank lever 35 has an operative connection with a collar 36 slidable upon the sleeve 23, the` two collars upon opiosite sides of the ullcy 20 being connected by arms 37 to a s ide 38. By properly adjusting the said slide the shoes 32 can be swung upon their pivots to throw either set of the pawls 33 into engagement with the driven shaft thereby reversed. A bell cranklever 39 is utilized for moving the slide 38 to adjust the clutch device and the -said bell crank lever is actuated by a bar 40 provided at one end with a notch 41 engaging a second crank arm 42 upon the lever shaft 18.

The crank arm 42 is disposed at approximately right angles to the crank 17 governing the track 8 and extends upwardly in an operative position when the said crank 17 projects rearwardly in alinement with the rod 16 and a dead center is produced between the latter two members as indicated in Figs. 2 and 5, the track sections 8a being then in an inoperative osition should the lever 19 be swung to the eft the crank 17 will move downwardl while should the said lever beI swung to tlie right the crank will move upwardly. In either instance however, the rod 16 4will be moved to the right and will operate through the medium of the crank arms 14 and links 13 to movev the slidable disk 7b awa from the disk 7a, thereby throwing the trac sections 8 out of alinement witli cach other. track sections will be thrown in an operative position regardless of whether the lever is moved to the right or left, but 'as hereinafter explained the driven member will be rotated in one direction in one instance and in an o osite direction in-the other instance. n

igs. 2 and 5 the pawls 33 at the left of the shoes 32 are in an operative position and should the lever 19 be swung to the right, the crank arm 42 will drop out of the iotch 41 without moving the bar 40 or in any manner interfering with the clutch mechanism.

The clutch device is in the nature of a of the driven shaftdepending upon which ,7.
